CONNECTION FOR LEAKDVOR OTHER LIKE PIPES.

SPECIFICATION forming part of Letters Patent No. 326,425, datedSeptember 15, 1885.

Application filed November 13. 1984. (No model.) Patented in EnglandFebruary 8, i884, No. 2,984, and Oct .ber 7, 1884, No. 13,284.

T LZZ whom it may concern:

Be it known that I, FRANK GEORGE, brassworker, a subject of the Queen ofGreat Britain and Ireland, and residing at 27 N orthumberland Street,Regents Park, in the county of Middlesex, England, have invented certainImprovements in Connections for Lead or other Like Pipes, (for which Ihave made applications in Great Britain, No. 2,984, dated February 8,1884, and No. 13,284, dated October 7, 1884,) of which the following isa specification.

My invention has for its object t0 provide a very simple and efficientmeans for connectf ing lengths of lead or other soft-metal pipestogether, or to gas-meters or other apparatus, without the necessity forusing solder or a number of auxiliary parts, such as `has hitherto beenthe practice. According to myinvention I provide for each end of thepipes to be joined a 'sleeve-piece, technically termed a lining,7 whichhas in its interior a double taper, so that thefront and hinder portions are slightly larger than the mid portions. In the interior of eachof these linings I form a number of grooves or recesses, preferably ol'a ratchet-tooth shape in section, the toothed or ledged part being presented toward the front part or outer end of the lining. On the end ofthe pipes t0 be joined being inserted into their linings and ataper-expander being driven into the said ends, the material of thepipes is driven into the grooves in the linings, and is caused to fillcomplete] y the interiors of the said linings with their double inclinesand grooves, so that the linings are by these means firmly iixed to thesaid pipes.

Figure 1 represents in longitudinal section a connection for twosoft-metal pipes made according t0 my invention. Fig. 2 is an externalview of the same. Fig. 3 shows a longitudinal section of the aforesaidlining. Fig. et shows the same with a pipe end inserted thereinpreparatory to expanding it thereinto, and Fig. 5 represents one of thesaid linings with a screw -socket of the ordinary kind formed on it forattachment to a ball, cock, or a tap or the like. Fig. 6 illustratespipes provided with the aforesaid linings attached to a -ing to myinvention attached to a T-piece, it

The lining A, Fig. 3, is made to the gage of the pipeto be fixedtherein, and is in its interior formed with a double taper-that is tosay, its internal diameteris smaller in the center a?, and widens out toa larger internal diameter at both the ends y z. In its interior areformed hollows, grooves. or recesses a, preferably of ratchet-toothform, as shown, the faces of the teeth being presented toward the end ofthe pipe. The said lining is passed over the end of the pipe B to be xedin the said lining, as shown in Fig. 4, and on a tanpin or expanderbeing driven into the end of the pipein the direction of the arrow, thepipe v is upset or expanded and lills the interior of the said liningand the hollows, grooves, or recesses therein, and owing to these andthe double taper aforesaid the said lining and pipe are iirml y joinedtogether. The said lining thus lixed to the pipe forms the means of 7oattachment of the pipe to another pipe or the like, such as the shortpipes projecting from gas-meters, or from ball cocks or valves or tapsor the like. Figs. 1 and 2 show two pipes connected by means of ascrewed collar or nut, or what is known as a union coupling.7 Thelinings on each ofthe pipes are alike in their interiors, but of coursethe one has on its exterior the ordinary iiange, and the other theordinary screw necessary for the said screwed collar or nut. Fig.l 5shows the lining formed with an internally-screwed socket forattac-hment to a tap or other apparatus; and Fig. 6 shows three pipesfitted with linings accord- 8 being understood that I do not limitmyself to 5 any particular means by which the linings fixed to pipesaccording to my invention are fixed together, or to the apparatus towhich they are to be connected. In order to render thehereinbeforedescribed l joint perfectly tight and secure, I prefer to xmake the following addition thereto: rIhe front end of one of thelinings is splayed or widened out, as shown at b, in Fig. 7, (which is alongitudinal section of two pipes connected by linings formed accordingto myinventiom) and over this splayed or widened-out part the extremeouter part of the material of the pipe end inserted into the said liningis spread by 10o the expander, as shown at c. The other lining has ataper-reduced end piece at itsforward part, as shown at d, which entersand bears upon the metal of the pipe splayed out at c, as aforesaid, atthe end of the opposed lining. The aforesaid taper reducedV end piece,d, maybe milled, ronghened, or toothed on its outside, so as to biteinto the soft metal of the splayed-out end c of the pipe in the opposedlining. The linings are secured together by means of a screw-collarcoupling or nut, as shown. or by any other convenient.

y a splayed or widened-out part, b c, as hereinbefore described,attached to a short pipe, f, project-ing from the apparatus-fagas-meter, for eXample-to which the pipe is to be con nected. Thenipple-piece d is in this case formed on the said short pipef.

Fig. shows a T-piece, to which are connecte-d pipes and linings formedwith splayed or widened-out parts b c, as hereinbet'ore desl-ribed, thenipplepieces din this ease being formed on each end of the T-piec-e, towhich the pipes are joined.

Fig. l1 shows a pipe and lining formed with a splayed or widened-outpart, b c, as hereinbefore described, and formed with an ordinaryscrew-socket for receiving the short screwed pipe or projection ol' aball-cock, a tap, or

the like, the nipplef in this case being formed at the end of the saidscrewed pipe or projection.

Having now described and particularly ascertained the nature of my saidinvention, and in what manner the same is to be performed, I declarethat what I claim is 1. The herein-described sleeve -piece forpipe-joints, said sleeve-piece having its interior diameter taperingoutward in both directions from a central point, and adapted to receivethe end of a softmetal pipe, substantially as set forth.

2. The herein described sleeve piece for pipe-joints` said sleeve-piecehaving its interior diameter tapering outward in both directions fromacentral point, and havin recesses in said interior surface into which te end of asoft-metal pipe can be expanded, substantially as described.

3. Apipejoint consisting of two pipe ends, each having a sleeve-,piecethereon., with an interior `surface tapered outward in both di.-rections, and a coupling-collar for the adjoin# ing pipe ends,substantxall y as specified.

4. The combination of lengths of sofbmetal pipe with sleeve-piecesthereon, having interior surfaces tapered outward in both directions,and one of said sleeve-pieces having a widened-out end, into which itspipe is upset, and the other sleeve-piece having a conical -end adaptedto such upset end of the pipe,

substantially as described.

In testimony whereof I have signed my naine to this specification in thepresence of two subscribing witnesses.
